Definitions

  • the present invention relates to occupancy and vacancy sensors for detecting an occupancy or a vacancy in a space, and more particularly, to a wireless load control system including a plurality of battery-powered occupancy or vacancy sensors for detecting an occupancy or a vacancy in a space, and a load control device for controlling the amount of power delivered to an electrical load in response to the occupancy or vacancy sensors.
  • Occupancy and vacancy sensors are often used to detect occupancy and/or vacancy conditions in a space in order to control an electrical load, such as, for example, a lighting load.
  • An occupancy sensor typically operates to turn on the lighting load when the occupancy sensor detects the presence of a user in the space (i.e., an occupancy event) and then to turn off the lighting load when the occupancy sensor detects that the user has left the space (i.e., a vacancy event).
  • a vacancy sensor only operates to turn off the lighting load when the vacancy sensor detects a vacancy in the space. Therefore, when using a vacancy sensor, the lighting load must be turned on manually (e.g., in response to a manual actuation of a control actuator).
  • Occupancy and vacancy sensors have often been provided in wall-mounted load control devices that are coupled between an alternating-current (AC) power source and an electrical load for control of the amount of power delivered to the electrical load.
  • wall-mounted load control devices typically comprise internal detectors, such as, for example, a pyroelectric infrared (PIR) detector, and a lens for directing energy to the PIR detector for detecting the presence of the user in the space.
  • PIR pyroelectric infrared
  • the wall-mounted load control devices are mounted to a wall in a standard electrical wallbox (i.e., replacing a standard light switch), the detection of energy by the PIR detector may be hindered due to the direction that the load control device is facing and by obstacles in the space, thus increasing the likelihood that the load control device may not detect the presence of a user.
  • Some prior art occupancy and vacancy sensors have been provided as part of lighting control systems. These sensors are typically coupled via a wired control link to a lighting controller (e.g., a central processor), which then controls the lighting loads accordingly. Since the control link is typically a low-voltage control link, these occupancy and vacancy sensors are not required to be mounted in electrical wallboxes, but may be mounted to the ceiling or high on a wall. Therefore, the occupancy and vacancy sensors may be positioned optimally to detect the presence of the user in all areas of the space.
  • these prior art lighting control systems require advanced system components and configuration procedures in order to operate properly.
  • a radio-frequency load control system with occupancy sensing comprises a load control device and first and second battery-powered occupancy sensors.

  • the remote occupancy sensors 120 are removably mountable to a ceiling or a wall, for example, in the vicinity of (i.e., a space around) the lighting load 104 controlled by the dimmer switch 110, and are operable to detect occupancy conditions in the vicinity of the lighting load.
  • the occupancy sensors 120 may be spaced apart to detect occupancy conditions in different areas of the vicinity of the lighting load 104.
  • the remote occupancy sensors 120 each include an internal detector, e.g., a pyroelectric infrared (PIR) detector 310 (Fig. 3), which is housed in an enclosure 122 (e.g., an enclosed plastic housing) and will be described in greater detail below.
  • the enclosure 122 comprises a lens 124 (e.g., an outwardly domed lens) provided in a front surface 125 of the enclosure 122 (which defines a top plate of the occupancy sensor 120).
  • the internal detector is operable to receive infrared energy from an occupant in the space via the lens 124 to thus sense the occupancy condition in the space.
  • the occupancy sensors 120 are operable to process the output of the PIR detector 310 to determine whether an occupancy condition (i.e., the presence of the occupant) or a vacancy condition (i.e., the absence of the occupant) is presently occurring in the space, for example, by comparing the output of the PIR detector 310 to a predetermined occupancy voltage threshold.
  • the internal detector could comprise an ultrasonic detector, a microwave detector, or any combination of PIR detectors, ultrasonic detectors, and microwave detectors.
  • Fig. IB is a simplified state diagram illustrating the operation of the occupancy sensors 120 of the RF lighting control system 100.
  • the occupancy sensors 120 each operate in an "occupied" state or a "vacant” state in response to the detections of occupancy or vacancy conditions, respectively, in the space. If one of the occupancy sensors 120 is in the vacant state and the occupancy sensor determines that the space is occupied in response to the PIR detector 310, the occupancy sensor changes to the occupied state.
  • the dimmer switch 110 may be assigned to (i.e., associated with) one or more remote occupancy sensors 120.
  • the remote occupancy sensors 120 transmit digital messages wirelessly via RF signals 106 to the dimmer switch 110 in response to the present state of the occupancy sensors.
  • a message transmitted by the remote occupancy sensors 120 may include a command and indentifying information, for example, a 52-bit serial number (i.e., a unique identifier) associated with the transmitting occupancy sensor.
  • the dimmer switch 110 is responsive to messages containing the serial numbers of the remote occupancy sensors 120 to which the dimmer switch is assigned.
  • the commands included in the digital messages transmitted by the occupancy sensors 120 may comprise an occupied command (e.g., an occupied-take-action command or an occupied-no-action command) or a vacant command.
  • the dimmer switch 110 is operable to turn on the lighting load in response to receiving a first occupied-take-action command from any one of the occupancy sensors 120.
  • the dimmer switch 110 is operable to turn off the lighting load 104 in response to the last vacant command received from those occupancy sensors 120 from which the occupancy sensor received either occupied-take-action or occupied-no-action commands. For example, if the occupancy sensors 120 both transmit occupied-take- action commands to the dimmer switch 110, the dimmer switch will not turn off the lighting load 104 until subsequent vacant commands are received from both of the occupancy sensors.
  • Each occupancy sensor 120 also comprises an ambient light detector 234 (Fig. 2B), e.g., a photocell, for detecting the level of ambient light around the occupancy sensor.
  • the occupancy sensor 120 only measures the ambient light level when an occupancy condition is first detected. The ambient light level is compared to a predetermined ambient light level threshold. If the measured ambient light level is less than the predetermined level when an occupancy condition is first detected by one of the occupancy sensors 120, the occupancy sensor transmits the occupied-take-action command to the dimmer switch 110. On the other hand, if the measured ambient light level is greater than the predetermined level when an occupancy condition is first detected, the occupancy sensor 120 transmits the occupied-no-action command to the dimmer switch 110. Accordingly, the dimmer switch 110 does not turn on the lighting load 104 if the ambient light level in the space is sufficiently high.
  • the occupancy sensor 120 While one of the occupancy sensors 120 continues to detect the occupancy condition in the space (i.e., a continued occupancy condition), the occupancy sensor regularly transmits the occupied-no-action command to the dimmer switch 110, such that the dimmer switch knows that the occupancy sensor 120 is still in the occupied state. In response to receiving the occupied-no-action command, the dimmer switch 110 either maintains the lighting load 104 on (e.g., if an occupied- take-action command was previously received) or maintains the lighting load off.
  • the occupancy sensors 120 are each characterized by a predetermined occupancy sensor timeout period TTI MEOUT , which provides some delay in the adjustment of the state of the occupancy sensor, specifically, in the transition from the occupied state to the vacant state.
  • the predetermined occupancy sensor timeout period T TIMEO U T may be user-selectable ranging, for example, from five to thirty minutes.
  • Each occupancy sensor 120 will not transmit a vacant command until the occupancy sensor timeout period T TIMEOUT has expired.
  • Each occupancy sensor 120 maintain an occupancy timer to keep track of the time that has expired since the last detected occupancy condition.
  • the occupancy sensors 120 periodically restart the occupancy timers in response to determining an occupancy condition (as shown by "Restart Timer" in the state diagram of Fig. IB).
  • the occupancy sensors 120 do not change to the vacant state, and the lighting load 104 is not turned off, in response to brief periods of a lack of movement of the occupant in the space. If the occupancy sensor 120 fails to continue detecting the occupancy conditions, the occupancy sensor 120 waits for the length of the occupancy sensor timeout period T TIMEOUT (as shown by "Wait” in the state diagram of Fig. IB). After the occupancy timer expires, the occupancy sensor 120 changes to the vacant state and transmits a vacant command to the dimmer switch 110 (as shown by "Timeout" in the state diagram of Fig. IB).
  • Fig. 1C is a simplified state diagram illustrating the state of the failsafe timer of the dimmer switch 110. The failsafe timer is started when the lighting load 104 is controlled from off to one and at least one occupancy sensor 120 is assigned to the dimmer switch 110. If there are not any occupancy sensors 120 assigned to the dimmer switch 110 when the lighting load 104 is turned on, the failsafe timer is not started.
  • the failsafe timer is reset to the value of the failsafe timeout period T FAILSAFE in response to receiving a digital message from any of the occupancy sensors 120 assigned to the dimmer switch 110 or in response to actuations of any the dimmer actuators (which do not cause the lighting load 104 to be turned off).
  • the failsafe timer expires, the dimmer switch 110 assumes that all of the occupancy sensors are in the vacant state and turns off the lighting load 104.
  • the failsafe timer is stopped whenever the lighting load 104 is turned off (i.e., when vacant commands are received from all occupancy sensors 120, when one of the dimmer actuators is actuated to turn off the lighting load, or when the failsafe timer expires).
  • the dimmer switch 110 controls the lighting load 104 in response to the received digital messages as well as actuations of the dimmer actuators (i.e., toggle actuator 114 and the intensity adjustment actuator 116) and the failsafe timer.
  • Fig. ID is a simplified state diagram illustrating how the dimmer switch 110 controls the state of the lighting load 104 (i.e., between on and off).
  • the dimmer switch 110 does not control the intensity of the lighting load 104 in response to the occupied-no-action commands.
  • the dimmer switch 110 turns on the lighting load 104 when the first occupied-take-action command is received or when one of the dimmer actuators is actuated to turn on the lighting load. Further, the dimmer switch 110 turns off the lighting load 104 when the last vacant command is received from the occupancy sensors 120, when one of the dimmer actuators is actuated to turn off the lighting load, or when the failsafe timer expires.
  • Fig. 2 A is a simplified block diagram of the dimmer switch 110.
  • the dimmer switch 110 comprises a controllably conductive device 210 coupled in series electrical connection between the AC power source 102 and the lighting load 104 for control of the power delivered to the lighting load.
  • the controllably conductive device 210 may comprise any suitable type of bidirectional semiconductor switch, such as, for example, a triac, a field-effect transistor (FET) in a rectifier bridge, or two FETs in anti-series connection.
  • the controllably conductive device 210 includes a control input coupled to a drive circuit 212. The input to the control input will render the controllably conductive device 210 conductive or non-conductive, which in turn controls the power supplied to the lighting load 104.
  • the drive circuit 212 provides control inputs to the controllably conductive device 210 in response to command signals from a controller 214.

Abstract

L'invention porte sur un système de commande de charge qui commande une charge électrique disposée dans un espace et comprend un dispositif de commande de charge et un ou plusieurs détecteurs de présence. Le dispositif de commande de charge commande la charge en réponse aux signaux de commande sans fil reçus à partir des détecteurs de présence. Chaque détecteur de présence transmet un signal de commande occupé au dispositif de commande de charge en réponse à la détection d'une condition de présence dans l'espace et un signal de commande vacant au dispositif de commande de charge en réponse à la détection d'une condition de vacance. Le dispositif de commande de charge active la charge en réponse à la réception du signal de commande occupé à partir d'au moins l'un des détecteurs de présence, et désactive la charge en réponse à la réception de signaux de commande vacants provenant des deux détecteurs de présence. Le dispositif de commande de charge est actionnable pour déterminer qu'aucun signal de commande sans fil n'a été reçu depuis les détecteurs de présence pour la durée d'une période de délai d'inactivité prédéterminée et pour ultérieurement désactiver la charge.
